Answer:

A. Below par.

Step-by-step explanation:

We have been given that 3 weeks ago John bought stock at 491/4; today the stock is valued at 497/8.

Let us find change in stock's value by subtracting present value from the value of stock 3 weeks ago.

\text{Change in stock's value}=\frac{497}{8}-\frac{491}{4}

Let us have a common denominator.

\text{Change in stock's value}=\frac{497}{8}-\frac{491\times 2}{4\times 2}

\text{Change in stock's value}=\frac{497}{8}-\frac{982}{8}

\text{Change in stock's value}=\frac{497-982}{8}

\text{Change in stock's value}=\frac{-485}{8}

We can see that stock's value has decreased, therefore, the stock is performing below par and option A is the correct choice.

La edad de Ericka es el tripl de la edad de Liliana y hace 9 años la suma de sus edades era 22. ¿Cuantos años tiene actualmente
Gnom [1K]

Answer:

Liliana tiene 10 años.

Step-by-step explanation:

Definamos las variables:

E = edad de Ericka

L = edad de Liliana.

Primero sabemos que la edad de Ericka es el triple de la edad de Liliana, entonces:

E = 3*L

Tambien sabemos que hace 9 años la suma de sus edades era 22

Hace nueve años la edad de Ericka era E - 9

Y hace nueve años la edad de Liliana era L - 9

Entonces tenemos:

(E - 9) + (L - 9) = 22

Así, tenemos un sistema de dos ecuaciones:

E = 3*L

(E - 9) + (L - 9) = 22

Queremos conocer la edad actual de Liliana.

Para ello tenemos que despejar E en una de las ecuaciones.

Podemos ver que en la primer ecaución E ya está aislada, entonces nos saltamos ese paso.

Ahora, reemplazamos E en la otra ecuación:

(E - 9) + (L - 9) = 22

(3*L - 9) + (L - 9) = 22

Ahora podemos resolver esto para L

3*L - 9 + L - 9 = 22

4*L - 18 = 22

4*L = 22 + 18

4*L = 40

L = 40/4 = 10

L = 10

Liliana tiene 10 años.

2)<br> 8xy -- 3y + 2 ( 9x - 5y + 4 ) if x = 3, y = - 4
Scilla [17]

Answer:

8xy-3y + 2(9x-5y+4) = 18

Step-by-step explanation:

We need to find the value of the given expression:

8xy-3y + 2(9x-5y+4) ....(1)

when x = 3 and y = -4

Put the values of a and y in equation (1)

8×3×(-4)-3(-4)+ 2(9×3-5(-4)+4)

= -96 +12 + 2(27 + 20 +4)

= -84 + 2(51)

= -84 + 102

= 18

Hence, the value of the given expression is 18.

What is the probability that a standard number cube will show a two, five, or six when it is rolled?
tia_tia [17]

Answer:

p=0.5

Step-by-step explanation:

A standard die has six numbers (1 through 6). That means there is a 1/6 probability of rolling any one number. There is a 3/6 probability of rolling one of the selected numbers which simplifies to 1/2 or 0.50
